Comment(by rouault):

 I have reviewed the differences in GDALCreateGenImgProjTransformer2() and
 the use made of it in PostGIS Raster code (2 occurrences in in rt_warp.c).
 I believe that there should be no impact on the one at line 358, but there
 might be an influence on the one at line 840 if the geotransform on the
 dest ds is set to [ 0, 1, 0, 0, 0, +/- 1 ]. If that's the case, I believe
 that you get a "Unable to compute a transformation between pixel/line and
 georeferenced coordinates for ..." error message from GDAL, and a NULL
 result, that causes rt_raster_gdal_warp() to return in error.

 Is it the case ?
